evidence from that hard drive. fbi working hard at quantico to try to piece that smashed computer back together again, to try to retrieve as much information to find what websites for example he might have visited. what about toxicology tests, what about friends he may have spoken to and given a sense of what he was thinking or his intentions or his plan? as you know since the beginning we've tried to find anyone who would call themselves a friend of his, certainly in recent years, we just haven't found any. they of course, authorities, have been interviewing family and relatives and friends of nancy lanza, the mother, to see what information they can get. certainly they must have talked to a doctor, if there was a family doctor involved, to find out was nancy lanza getting any help? was she trying to take care of her son on her own? was he in fact getting any counseling for anything? was he on medications? if so, was he taking them? of course that very thing in the end was what we hoped to find out when those toxicology reports come out in a few weeks? >> lots of focus on the mother.
